  • Abstract
    A passive lossless turn-on/turn-off snubber network is proposed for the boost PWM converter. Besides the benefit of small number of added components, all the devices block the voltage no more than the output DC voltage. The operation principle and design guideline is presented. Experimental results demonstrate that for 1 kW PFC AC/DC boost converter, the proposed snubber circuit can achieve significant efficiency improvement over the hard-switching converter
